Question

I have a simple question about how to format a string.

I have this number as a string “01234567890”, with zero on left, and need to format that to be like that “012.345.678-90“.

I solved it using it

char[] charArgs = sCPF.ToCharArray();

return String.Format("{0}{1}{2}.{3}{4}{5}.{6}{7}{8}-{9}{10}", 
                     charArgs[0], charArgs[1], charArgs[2], charArgs[3], 
                     charArgs[4], charArgs[5], charArgs[6], charArgs[7], 
                     charArgs[8], charArgs[9], charArgs[10]);

I also tried that :

Convert.ToInt64("01234567890").ToString("000.000.000-00")

but that gives me “1234567890,000000-00”

But if I also tried this

Convert.ToInt64("01234567890").ToString("000-000-000-00")

which results in “012-345-678-90”, but is not what I need in this case, where I need the dots (.).

Are there a better way to do it?

I am using .net 2.0.

You were almost there.

Try this:

Convert.ToInt64("01234567890").ToString(@"000\.000\.000-00")

That gives me: 012.345.678-90
